# Breeding Logic

\
Only male racehorses (i.e. colts or stallions can) can be placed into the Stud Farm for 1, 3 or 7 days. Once your racehorse is in Stud Farm, it cannot be taken out until that breeding period is complete.

As a male racehorse owner, you can determine the breeding price you want to charge. If a female racehorse (i.e. filly or mare) decides to breed with your male racehorse, the male racehorse keeps the stud fee and the female racehorse receives the offspring.
